Resumen: Introducción: A pesar de la efectividad de los tratamientos inyectables para la esclerosis múltiple (EM), las reacciones adversas y el dolor pueden implicar problemas de satisfacción y adherencia. Se presenta la validación de la versión española del Multiple Sclerosis Treatment Concerns Questionnaire (MSTCQ)©, que evalúa la satisfacción con el dispositivo de autoinyección (DA), 4 dimensiones: sistema de inyección (A), efectos secundarios (B) (síntomas pseudogripales, reacciones, satisfacción), experiencia con el tratamiento (C) y beneficios (D). Métodos: Dos fases de estudio: 1) Adaptación cultural con expertos (n = 6) y pacientes (n = 27). 2) Estudio observacional, transversal y multicéntrico de validación. Se evaluaron 143 pacientes adultos con EM que utilizaban el DA Extaviject™30G. Cuestionarios: MSTCQ©; Patient-Reported Indices for Multiple Sclerosis (PRIMUS©), y Treatment Satisfaction Questionnaire for Medication (TSQM©). Propiedades psicométricas: factibilidad (% casos válidos y distribución de puntuaciones); fiabilidad (α-Cronbach) y test-retest (n = 41, coeficiente correlación intraclase [CCI]), y validez de constructo (análisis factorial A y B, [AF]) y convergente (Spearman-rho MSTCQ© versus TSQM©). Resultados: Edad media (DT) 41,94 (10,47) años, 63% mujeres, 88,11% con EM remitente-recurrente, media (DT) EDSS 2,68 (1,82) puntos. Alta cumplimentación del MSTCQ© (perdidos 0-2,80%). Alta consistencia interna: puntuación total (A + B) α = 0,89, por dimensiones (A, B y C) α = 0,76, 0,89 y 0,92, respectivamente. Excelente concordancia test-retest en las puntuación total (CCI = 0,98), por dimensiones (A, B y C) CCI = 0,82, 0,97 y 0,89, respectivamente.

Introduction: Although subcutaneous treatments for multiple sclerosis (MS) have been shown to be effective, adverse reactions and pain may adversely affect treatment satisfaction and adherence. This study presents an adapted and validated Spanish version of the Multiple Sclerosis Treatment Concerns Questionnaire© (MSTCQ), which evaluates satisfaction with the injection device (ID) across 4 domains: injection system (A), side effects (B) (flu-like symptoms, reactions, and satisfaction), experience with treatment (C) and benefits (D). Methods: Two study phases: (1) Cultural adaptation process with input from experts (n = 6) and patients (n = 30). (2) Validation obtained by means of an observational, cross-sectional, multi-centre study evaluating 143 adult MS patients using an ID. Tools employed: MSTCQ©, Patient-Reported Indices for Multiple Sclerosis (PRIMUS©), and Treatment Satisfaction Questionnaire for Medication (TSQM©). Psychometric properties: Feasibility (percentage of valid cases and floor/ceiling effects); Reliability (Cronbach α) and test–retest correlation (n = 41, intraclass correlation coefficient, ICC); and construct validity (factor analysis of domains A and B) and convergent validity (Spearman rank-order correlation for MSTCQ© vs TSQM©). Results: Mean age (SD) was 41.94 (10.47) years, 63% of the group were women, and 88.11% presented relapsing-remitting MS. Mean (SD) EDSS score was 2.68 (1.82) points. MSTCQ© completion was high (0%-2.80% missing data). Internal consistency was high at α = 0.89 for the total score (A + B) and α = 0.76, 0.89, and 0.92 for domains A, B, and C, respectively. The version demonstrated excellent test–retest reliability for the total (ICC = 0.98) and for domains A, B, and C: ICC = 0.82, 0.97, and 0.89, respectively. Factor analysis corroborated the internal structure of the original questionnaire. The association between total and domain scores on both the MSTCQ© and the TSQM© was moderately strong (Rho = 0.42-0.74) and significant (P

Introduction and objective: Teriflunomide is an oral immunomodulatory agent approved for the treatment of relapsing–remitting multiple sclerosis (RRMS). We examined teriflunomide outcomes in patients with RRMS under clinical practice conditions in Spain. Material and methods: Non-interventional, retrospective study at 15 sites in the Autonomous Region of Madrid and nearby regions. Effectiveness (relapses, EDSS, gadolinium-enhancing T1 lesions and new/enlarged T2-weighted lesions), safety (adverse events), and reasons for discontinuation during the 24 months after teriflunomide initiation were reported. Results: A total of 776 patients were included (mean [SD] age was 43.3 (9.8) years; 69.3% were female). Two-thirds (67.7%) of patients had received a prior treatment, with beta-interferons or glatiramer acetate (BRACE) as the most frequent (93.5%) treatment. After 24 months, teriflunomide significantly reduced the annualized relapse rate (ARR) by 72% (mean [95% confidence interval] 0.12 [0.10, 0.14] vs 0.43 [0.40, 0.47] at baseline; P

Objective: To ascertain the changes of serum neurofilament light chain (sNfL) and glial fibrillary acidic protein (sGFAP) values in relapsing-remitting multiple sclerosis (RRMS) patients treated with ocrelizumab and their association with treatment response., Methods: Multicenter prospective study including 115 RRMS patients initiating ocrelizumab treatment between February 2020 and March 2022 followed during a year. Serum samples were collected at baseline and every 3 months to measure sNfL and sGFAP levels using single-molecule array (SIMOA) technology. Based on age and body mass index, sNfL values were standardized using z-score. NEDA (non-evidence of disease activity)-3 status was defined for patients free of disease activity after a year of follow-up. Inflammation (INFL) was considered when new relapses occurred during follow-up or new MRI lesions were found at 1-year exploration. PIRA (progression independent of relapse activity) was defined as disability progression occurring in the absence of relapses or new MRI activity., Results: After a year on ocrelizumab, 85 patients (73.9%) achieved NEDA-3. Thirty patients did not achieve NEDA: 20 (17.4%) because of INFL and 10 (8.7%) because of PIRA. Of INFL patients, 6 (30.0%) had relapses, and 17 (85.0%) had at least one new MRI lesion at the 12-month examination. At baseline, INFL patients had higher sNfL (p = 0.0003) and sGFAP (p = 0.03) than the NEDA-3 group. PIRA patients mostly exhibited low sNfL and heterogeneous sGFAP levels. After a year, NEDA-3 and INFL patients showed similar decreases in sNfL (p < 0.0001) and sGFAP (p < 0.0001 for NEDA-3 and p = 0.001 for INFL ones). However, the decrease occurred earlier in NEDA-3 patients. Accordingly, sNfL > 1.5 z-score 3 months after ocrelizumab initiation indicated a higher risk of inflammation (OR = 13.6; p < 0.0001). Decrease in sGFAP values occurred later in both groups, with significant reductions observed at 12 months for INFL and 6 and 12 months for NEDA-3. No significant changes in sNfL or sGFAP were observed in PIRA patients., Conclusion: Ocrelizumab induced normalization of sNfL and sGFAP in the majority of NEDA-3 and inflammatory patients but did not cause changes in the PIRA group. Our data suggest that normalization of sNfL and sGFAP is associated with the lack of inflammatory-associated disease progression but it may not affect non-inflammatory PIRA., Competing Interests: FR-J received research grants and travel support for speaking engagements from Janssen, Biogen, Novartis, Roche, Sanofi-Genzyme, Bristol-Myers-Squibb and Merck.

Background: Risk attitude is defined as the willingness to tolerate risk to achieve a greater expected return. Limited information is available on how relapsing-remitting multiple sclerosis people's perceptions about disease trajectory and risk attitude may influence treatment choices., Methods: A non-interventional study applying principles of behavioral economics was conducted to assess willingness to receive unwarranted high-efficacy disease-modifying therapy (DMT) according to best-practice guidelines. People with relapsing-remitting multiple sclerosis (PwRRMS) according to 2010 McDonald criteria completed a survey on symptom severity, risk preferences, and management of simulated case scenarios mimicking the current treatment landscape. PwRRMS's choice for high-efficacy agents was established as the participant's selection of monoclonal antibodies for case scenarios with at least 2 years of clinical and radiological stability., Results: A total of 211 PwRRMS were studied (mean age 39.1 ± 9.5 years, 70.1% female, mean Expanded Disability Status Scale score 1.8 ± 1.1). Almost 50% (n = 96) opted for a high-efficacy DMT despite the lack of evidence of disease activity. Younger age and risk-seeking behavior were associated with an increased likelihood of selecting unwarranted high-efficacy DMT [odds ratio (OR) 2.00, 95% confidence interval (CI) 1.02-3.93, p = 0.043, and OR 2.17, 95% CI 1.09-4.30, p = 0.027, respectively]. Clinical characteristics or subjective perception of symptom severity had no influence on participants' treatment choices., Conclusion: Identifying PwRRMS with risk-seeking behavior would be crucial to implementing specific educational strategies to manage information on disease prognosis, treatment expectations, and safety risk knowledge.

Objective: Pivotal trial have shown that patients with multiple sclerosis (MS) receiving ocrelizumab had better outcomes. However, data on ocrelizumab in clinical practice are limited. The aim of this study was to evaluate the preliminary safety profile and effectiveness of ocrelizumab treatment for multiple sclerosis (MS) in a real-world clinical setting., Methods: We conducted a retrospective study including consecutive patients from nine public hospitals in south-eastern Spain who received ocrelizumab after it was approved., Results: A total of 228 MS patients were included (144 with relapsing-remitting MS [RRMS], 25 secondary progressive MS [SPMS], and 59 primary progressive MS [PPMS]). Median follow-up period was 12 months (range, 1-32). No evidence of disease activity (NEDA) status at year 1 was achieved in 91.2% of the relapsing MS (RMS) population, while disability progression was detected in 37.5% of the PPMS patients (median follow-up period, 19 months). The most common adverse events reported were infusion-related reactions and infections, with the most common infections being urinary tract infections followed by upper respiratory infections and COVID-19., Interpretation: The preliminary results in our real-world setting show that ocrelizumab presented excellent results in suppressing disease activity with a favorable and consistent safety profile., (© 2020 The Authors.

Introduction: Although subcutaneous treatments for multiple sclerosis (MS) have been shown to be effective, adverse reactions and pain may adversely affect treatment satisfaction and adherence. This study presents an adapted and validated Spanish version of the Multiple Sclerosis Treatment Concerns Questionnaire © (MSTCQ), which evaluates satisfaction with the injection device (ID) across 4 domains: injection system (A), side effects (B) (flu-like symptoms, reactions, and satisfaction), experience with treatment (C) and benefits (D)., Methods: Two study phases: 1) Cultural adaptation process with input from experts (n=6) and patients (n=30). 2) Validation obtained by means of an observational, cross-sectional, multi-centre study evaluating 143 adult MS patients using an ID. Tools employed: MSTCQ © , Patient-Reported Indices for Multiple Sclerosis (PRIMUS © ), and Treatment Satisfaction Questionnaire for Medication (TSQM © ). Psychometric properties: Feasibility (percentage of valid cases and floor/ceiling effects); Reliability (Cronbach α) and test-retest correlation (n=41, intraclass correlation coefficient, ICC); and construct validity (factor analysis of domains A and B) and convergent validity (Spearman rank-order correlation for MSTCQ © vs TSQM © )., Results: Mean age (SD) was 41.94 (10.47) years, 63% of the group were women, and 88.11% presented relapsing-remitting MS. Mean (SD) EDSS score was 2.68 (1.82) points. MSTCQ © completion was high (0%-2.80% missing data). Internal consistency was high at α=0.89 for the total score (A+B) and α=0.76, 0.89, and 0.92 for domains A, B, and C, respectively. The version demonstrated excellent test-retest reliability for the total (ICC=0.98) and for domains A, B, and C: ICC=0.82, 0.97, and 0.89, respectively. Factor analysis corroborated the internal structure of the original questionnaire. The association between total and domain scores on both the MSTCQ © and the TSQM © was moderately strong (Rho=0.42-0.74) and significant (P<.05 and P<.01)., Conclusion: The Spanish version of MSTCQ © demonstrates appropriate psychometric properties., (Copyright © 2014 Sociedad Española de Neurología.
